Answer:

Explanation:

1. It is difficult to recycle polyvinyl chloride into plastic bags because it is a very hard plastic. Polyvinyl chloride is a widely used plastic because it is durable and stable with an average life span of 30 years.

2.  HDPE is a good material for boats because of its high tensile strength and low density. HDPE stands for High-density polyethylene. It is lightweight and impervious to damage.

3. HDPE. This is because it is unaffected by alkaline solution. It's corrosive nature gives it resistance to damage.

4. HDPE is used in making plastic lumber.

  It is also used in producing geomembrane.

5. To separate the mixture of PETE and HDPE, you would need to employ the flotation method of separating mixtures. Mixtures are separated based on their hydrophobic and hydrophilic abilities. The mixtures are placed in a condensed tube, and stirred. The substance with a lighter weight stays at the top while the heavier one stays below. They are then removed separately.

Indicate the peptides that would result from cleavage by the indicated reagent: a. Gly-Lys-Leu-Ala-Cys-Arg-Ala-Phe by trypsin b.
Ilia_Sergeevich [38]

Answer:

a. Gly-Lys + Leu-Ala-Cys-Arg + Ala-Phe

b. Glu-Ala-Phe + Gly-Ala-Tyr

Explanation:

In this case, we have to remember which peptidic bonds can break each protease:

-) <u>Trypsin</u>

It breaks selectively the peptidic bond in the carbonyl group of lysine or arginine.

-) <u>Chymotrypsin</u>

It breaks selectively the peptidic bond in the carbonyl group of phenylalanine, tryptophan, or tyrosine.

With this in mind in "peptide a", the peptidic bonds that would be broken are the ones in the <u>"Lis"</u> and <u>"Arg"</u> (See figure 1).

In "peptide b", the peptidic bond that would be broken is the one in the <u>"Phe"</u> (See figure 2). The second amino acid that can be broken is <u>tyrosine</u>, but this amino acid is placed in the <u>C terminal spot</u>, therefore will not be involved in the <u>hydrolysis</u>.

When road contractors are laying cement,they first place a series of steel rods in a specific patterns. the they pour the cement
Anna11 [10]
The steel rods will enable the concrete to form without any bumps and it will add shape to the cement and strength, so no odd massive lumps are formed.

That is what I think anyways :)

Which statement is most consistent with the plum pudding model of the atom?
lianna [129]
The answer to this question would be: <span>1) Electrons occupy regions of space
</span><span>
In plum pudding model, the atoms are drawn as pudding and the negative particle is spread around the pudding. In this model, the electron is spread but not moving in orbit. Rutherford model that comes afterward is the one that says most of the atoms is empty space.</span>
